Answer:
-3/2
Step-by-step explanation:
the formula for slope is y1-y2/x1-x2
where
y1 is the first point's y coordinate
x1 is the first point's x coordinate
y2 is the second point's y coordinate
x2 is the second point's y coordinate
so now we can plug our points in
-1-(-7)/1-5
6/-4
simplify
-3/2
Answer:
Step-by-step explanation:
